Data port pins 7 and 15 provide a relay that closes when an alarm is
sounding on the monitor. Pins 8 and 15 provide a relay that opens
when an alarm is sounding. Pin 15 is a common lead for both relays.
The relay operates whether the monitor is operating on AC power or
battery.
The N-595 data port provides analog voltage outputs between pins 6,
13, 14, and ground (pin 10), which can be used to calibrate
instruments such as a chart recorder. The voltage represents a specific
measured parameter's current value. The voltage differential varies
proportionally from 0 to 1 volt as the pin's parameter varies over its
full range of values, as indicated in Table 6 on page 97.
